Description

Cistern for toilet water-saving cistern

Technical field

The utility model belongs to the water-closet for bowl field, relates to a kind of toilet and pan cistern for toilet water-saving cistern.

Background technology

Lack of water is the ubiquitous problem in each city of China and rural area, and water saving must be done from national people.With the most closely-related water-closet for bowl water tank of people's lives be exactly a water rich and influential family, government expressly provides the tank for excrement pan ban use of from now on more than 9 liters.Existing toilet and pan cistern, the water capacity of its water tank are to design according to flushing stool institute water supply volume, no matter be that flushing is defecated or urine all is one case water, so just cause the huge waste of water resource.Because urine is measured little and is liquid, be easy to be washed out, just can rinse well with low amounts of water.Through experiment, flushing once urine is just enough with the water of 1/4-1/3 in the water tank, will waste 3/4-2/3 case water if use existing Cistern flushing once to urinate.Rough calculation, defecate once in next sky of people's normal condition, and urine is no less than 6 times, will waste 6 * 3/4=4.2 case water so in one day, and 1 year is exactly 4.2 * 365=1533 case water.The present inventor carries out measured result to the water tank of 460 * 170 * 335mm, the weight of one case water is about 10 kilograms, 1533 casees * 10 kilogram=15330 kilograms so, promptly a people will waste 15 tons of water in 1 year, the city of millions of populations just wasted the water that the water works produces in 1 year.As seen it is huge that existing water tank causes the waste of water resource.

Summary of the invention

The purpose of this utility model is to solve above-mentioned the problems of the prior art and provides a kind of simple in structure, and is easy to use, economical and practical, is provided with the cistern for toilet water-saving cistern of artificial control automatic water saving device.

The technical solution adopted in the utility model: a kind of cistern for toilet water-saving cistern, comprise small water-cup pipe, spanner, water tank, case lid, upper hose, handle, it is characterized in that being provided with in the water tank automatic water saving device that connects firmly with small water-cup pipe.Automatic water saving device comprises the locating support that connects with small water-cup pipe, and locating support is sleeved on the pull bar, and spring is arranged on the pull bar, and pull bar one end and connecting rod connect, and the other end and water-saving valve connect.Hanger is arranged on the center of water-saving valve.Connecting rod and spanner connect.Pull bar connects with handle.

The utility model is the improvement to existing toilet and pan cistern, in water tank, be provided with artificial control automatic water saving device, by the opening time of artificial control water-saving valve, give different discharging quantity of water to the different things that is rinsed respectively, solved not distinguish and be rinsed the thing type, no matter be that flushing stool or urine are all washed out one case water without exception at every turn, cause the problem of water resource huge waste.No matter whether people have consciousness of saving water to use the utility model, all can play the effect of automatic water-saving, compare with using existing water tank, but reduce water consumption about 60%.The utility model is simple in structure, and is easy to use, economical and practical, is applicable to the production and the transformation of existing toilet and the new and old cistern of pan.

The specific embodiment

Embodiment 1

Consult Fig. 1, Fig. 2, shown in Figure 3, present embodiment is a link-type control cistern for toilet water-saving cistern, seeing the water tank internal construction from the front, mainly is that the automatic water saving device that is made of connecting rod 1, pull bar 2, spring 3, metal ring 4, water-saving valve 5, locating support 6, screw 7 etc. and existing small water-cup pipe 8, spanner 9, water tank 10, case lid 11, upper hose 14, handle 15 constitute.Its automatic water saving device is arranged in the water tank 10, connects firmly with small water-cup pipe 8, is provided with case lid 11 above the water tank 10.The pull bar 2 of automatic water saving device is provided with spring 3, and spring 3 lower ends are fixed on the pull bar 2, and pull bar 2 is used to start and cuts out water-saving valve 5, and spring 3 is critical pieces of control automatic water saving device, restriction people's operating process.Locating support 6 one ends are sleeved on the small water-cup pipe 8, connect firmly by screw 7, two pipe rings 12 of the other end are sleeved on spring 3 positions on the pull bar 2, spring 3 is between two pipe rings 12, the effect of locating support 6 is positions of steady brace 2 and limits spring 3 strokes, can not all around swing when making pull bar 2 work, water-saving valve 5 can accurately be opened and closed.Pull bar 2 one ends connect by metal ring 4 and connecting rod 1, and the other end connects by the hanger 13 of metal ring 4 with water-saving valve 5, and hanger 13 is arranged on the center position of water-saving valve 5, and no longer hangs up with small water-cup pipe 8, and water-saving valve 5 can freely be moved up and down.Spanner 9 connects with connecting rod 1.

Consult shown in Figure 4ly, the EF dotted line is the position of existing water tank connecting rod among the figure, and small water-cup pipe 8 and upper hose 14 are arranged on and are prior art in the water tank 10.The E that turns round that the utility model will have connecting rod now extends to the A point, makes the A point parallel with water tank wall D point line with water tank spanner C point with water-saving valve 5 center B point lines, forms a rectangle.Its objective is when pulling spanner with hand because that connecting rod 1 and spanner are in is parallel, just easily accurately the drive pull bar move up and down, start and close water-saving valve 5.

Embodiment 2

Consult Fig. 5, shown in Figure 2, present embodiment is a hand pulling type control cistern for toilet water-saving cistern, the automatic water saving device of seeing water tank inside from the front is basic identical with embodiment 1 structure, different is that the case lid 11 above the water tank 10 is passed in pull bar 2 upper ends, its handle 15 direct and pull bar 2 connections, do not need connecting rod, pulling handle 15 can directly drive pull bar 2 and move up and down, and operates easier.

Operating principle of the present utility model: when pulling spanner 9 downwards with hand or upwards during pulling handle 15, driving pull bar 2 moves upward, driving water-saving valve 5 simultaneously opens, begin bath, the spring restriction that is subjected to locating support 6 at this moment is forced to compression, has produced the spring energy, in case loose one's grip, spring can just force pull bar 2 to move downward, and water-saving valve 5 is closed automatically, stops bath.If the water in the water tank 10 are all washed out, just can not loose one's grip, wait until that always the interior water of water tank has dashed till.Under the normal condition, people are unwilling to do like this, have been rinsed in the closet totally as long as see, will loose one's grip naturally, close water valve automatically, have the function of automatic water-saving, no matter whether people have consciousness of saving water, as long as this cistern for toilet water-saving cistern is installed, just can play the effect of water saving.Opening time by control water tank water-saving valve gives different discharging quantity of water to the different things that is rinsed respectively, and when just flushing was defecated, water supply volume was big, it is long to pull the spanner time, uses the water of full case, and during flushing urine, water supply volume is little, pulls spanner time weak point, uses a spot of water.Because urine often, thereby reach the purpose of a large amount of water savings.Can be widely used in the production and the transformation of existing toilet and the new and old cistern of pan.
